MOLD-ACTUATING- MECHANISM FOR TYPE-MACHINES.

To all whom it may concern:

Be it known that I, FRANK Trimaran PIER- i'ox'r, a citizen of the UnitedStates, temporarily residing at Horley, county of Surrey, llngland. haveinvented a certain new and useful Improvement in Mold-Actuatingfvlcchanism for Type-Machines; and I do hereby declare the following tobe a full, clear, andexact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the figures and letters of reference marked thereon.

This invention relates to that class of type casting machines whereinthe mold is equipped with a divided mold-blade the sections whereof areindependently movable for the production of low body type, and it hasfor its objectto improve the mold and simplify and render more certainthe actuating mechanism controlling the relative 1 positions oradjustments of the mold-blade l sections, as hereinafter described, thenovel features being pointed out in the claims. i

In the accompanying drawings illustratl ing a preferred form ofembodiment, Figi ure 1 is a side elevation of a portion of a i typecasting machine with the improvedi actuating mechanism applied thereto,a pori tion of the latter being in section on the line 1-1, of Fig. 4.Fig. 2 is atop plan view l and Fig. 8 is a right hand side elevation ofthe devices, Fig. 1. Fig. st is a top plan l view, partly in section,showing the mold l equipment. Fig. 5 is an enlarged sectional l view ofthe hold taken on line 2-2, of Fig. 1. Fig. 6 is a perspective view ofthe l mold-blade sections detached and separated. 1

Like letters of reference in the several figures indicate the sameparts.

As illustrated, the improvements althougl equally applicable to otherforms, are spe cially designed for use in connection with the typecasting machine of Patent No. i 625,998, dated May 30, 1899, whereof Xis i a portion of the bridge supporting the ceni tering pin (not shown)and die-case O. l The type mold is preferably like that of 1 Patent No.752,81 l, dated Feb. 23, 190A, of i which A represents the frame or baseplate, A the side blocks, and A the cross-block, and the dividedmold-blade with which it is equipped is similar to that of a companion iapplication, Serial No. 397,409, filed Octo- 1 ber 14, 1907, of which Bis the body or main l Specification of Letters Patent.

section and C the overlying r cut-off section provided with a web orplate a extending along one side of the body section within Instead,however, of providing the main section B with a rear extension for thecross-pin, and the cut-off section C with a vertical extension for theattachment of its actuating mechanism, both sections are formed of thesame length over all so that when their rear ends are in the samevertical plane their front or casting faces will be in alinement. Themain blade B is also furnished in its rear portion with an opening B inwhich is fitted a shouldered portion B of an actuating block or head Bthe latter riding in a seat formed in a fixed member E and provided witha rear extension B preferably in alinement with the mold-blade channel,for the reception of the actuating and adjusting mechanism of thecasting machine proper. As illustrated said extension B is provided withan orifice B for the reception of the usual cross pin. The cut-offsection G is in like manner provided with an opening 0 in which isfitted the shouldered portion of a block C hen the sections B, C, areassembled with blocks B and C in position, as indicated in Figs. 4 and5, said blocks are held from lateral displacement by the engagement oftheir outer faces with the walls of a groove or channel formed in memberE afliXed to or formed integral with the rear flange of base plate A,which flange is also preferably cut away as shown for the accommodationof head B Block C with its shouldered portion fitted to and filling theopening C in cut-off section C is formed with a transverse orificeprovided with opposite beveled surfaces C C for the reception of thecorrespond ingly beveled surfaces of oppositely disposed bolts D Darranged to reciprocate longitudinally in a direction transverse to themold-blade sections.

Bolt 13* is mounted in bearings in fixed member E and when advanced toenter the orifice in block C its beveled end engages the beveled surface0 and operates by its wedging action to advance the cut-off section Oagainst cross-block A thereby closing the end of the mold-cavity when ashort body type is desired. Bolt D is mounted upon and takes its bearingin block B and enters the orifice in block C on the opposite side frombolt D and 'it engages beveled surface C in a manner to retract thecut-oil section C and seat its rear end against the gaging surface B ofhead B thus holding the two mold-blade sections with their casting facesin alineinent, which is the position they assume when full body orcharacter type are desired. The projection and seating of bolt D whilerestraining movement of the cut-off section C, does not interfere withthe movement of the body section B, which latter is free to respond tothe regular adjusting devices applied to head B and. the withdrawal ofbolt D and engagement of bolt D with block C has the effect of lockingboth mold-blade sections upon the head B for simultaneous adjustment,said head B providing an ample bearing for bolt D as well as a shoulderor gage B for alining the casting faces of the two sections. The frontstop for the mold-blade sections is with a hardened block E detachablyapplied to the rear flange of bed plate A in position to be engaged byblock C when the mold blade sections or either of them are advanced intocontact with the face of cross-block A thus permitting shortermold-blade sections to be employed and avoiding the presence of theusual front stop opening.

It is the intention that bolts D D should alternately engage block 0-,to which end they are connected to a member D supported to reciprocatetransversely of the mold-blade sections in bearings formed between fixedmember E and base plate A. This member D is furnished with upwardlyextending cheek pieces D D on opposite sides of blocks 13 and CE. Thecheek piece D is provided with a socket for the reception of thethreaded end of bolt D while cheek piece D is provided with a groove Din which is received a flange or collar D on bolt D The groove D is inparallel with the mold-blade channel, to permit independent lateralmovement of bolt D the latter being supported in and moving with block Bseated in the body section B.

A spring F is applied to member D in a manner to normally project bolt Dinto engagement with its seat in block C and at the same time retractbolt D' thereby causing bolt sections B, C, to be locked upon head BThis is the position for casting full body or character type. \Vhenshort body type or quads are desired, it is only necessary that member Dshall be advanced against the tension of its spring F, to withdraw boltD and engage bolt D advancing responds to the dimension adjustingdevices.

The actuating mechanism for automatic ally advancing member D whenever alow quad or space is called for includes as its thereby and locking cutoff section C and releasing body section. B so that it alone principal,elements a motor device arranged to act upon. said member D inopposition to or suspending the action of said. motor device; trippingdevices for said restraining or suspending means operating to release orenergize the motor device and means for returning or restoring theenergy of said 1notor device.

In the preferred form of embodiment illustrated the motor device isrepresented by a plunger G supported in guides on a bracket R the latterdetachably secured to the bridge X or other suitable part of the casingmachine frame; a motor spring H interposed between the bracket and anadjustable head G and a lever K pivoted at K and having one arm inposition to engage a projecting portion D of member D and the other armcoupled by a link K to plunger G. The arrangement is such that thesuperior tension of motor spring H, if uin'estrained, will overcomeretracting spring F and shift member D in a direction to en gage bolt Dand disengage bolt l The restraining or suspending means for the motordevice is represented by a latch J pivoted at J to the bracket P inposition to engage a shoulder J on plunger G, and thereby preventmovement of said plunger in a direction to actuate member D, said latchJ being advanced by suitable means to engage shoulder J as by a spring Linterposed between the bracket and a shoulder on red L, the latterpivotally connected to said latch. The tripping device for rendering themotor active is represented by a shaft I? mounted in bearings on bracketP and provided with an arm M coupled to rod L, and one or more arms N inposition to be engaged by die case O when tl e latter is brought to theposition or positions assigned to low quads or spaces. The motorrestoring means is represented by a lever P pivoted at P on the bracketwith one arm I in position to engage plunger G in a direc tion tocompress its motor spring and restore latch J, the other arm of saidlever eXtending above and in position to be engaged by a moving part ofthe casting machine, such as the centering pin lever B.

The operation is as follows :As is well i known the matrix carrier ordie-case O is {movable in two directions in a horizontal plane to bringits various matrices succes- J sively into position opposite the mold,and l l when moved into position to cast spaces it contacts with one ofthe arms l thereby rocking shaft N in the direction indicated by thearrow in Fig. 3. The effect of this is to I withdraw latch J fromshoulder J thereby releasing plunger G which is immediately I drivenupward by spring H and causes the advance of member D against thepressure l of its retracting spring F. Bolt D is thereits retractingspring; means for restraining I by withdrawn from and bolt D intoengagement with block C whereby the cut-off section C is advanced toclose the mold. This advance of the cut-off section C takes place duringthe first part of the descent of centering pin lever B while theadjusting devices are operating to position the body section B, and iscompleted before the selected matrix is seated upon the mold. The casthaving been made, upon the rise of lever R, incident to the withdrawalof the matrix from the mold, lever P is engaged to return plunger G intoposition to reengage latch J, thereby not only restoring the power ofmotor spring H but positively withdrawing connecting lever K so thatmember D, responding to its spring, is automatically shifted back tonormal position, with the two mold-blade sections locked in position onhead B If the next succeeding type called for is a full body orcharacter type the shifting of the die case incident to the selection ofthe matrix permits latch J to engage shoulder J so that upon the nextdescent of lever It the action of motor spring it will be suspended, andthe two moldblade sections being locked to block B with their castingfaces in alinement will be moved in unison by the adjusting devicesconnected to said block.
